详细信息:Methylation of cytosines located 5' to guanosine is known to have a profound effect on the expression of several eukaryotic genes (Bird, 1992). In normal cells, methylation occurs predominantly in CG-poor regions, while CG-rich areas, called CpG islands, remain unmethylated. Aberrant methylation of normally unmethylated CpG islands has been documented as a relatively frequent event in immortalized and transformed cells (Antequera, 1990) and has been associated, CpG WIZ™ RARβ2 Amplification Kit
